Manley VOXBOX - MVBXA 4/2003 - Manual (Page 10)

H. LINE INPUT. XLR For balanced or unbalanced +4 line level sources. Transformer coupled. The PIN-
OUT is:
PIN 1 = CIRCUIT GROUND = SHIELD
PIN 2 = HOT = positive going signal +
PIN 3 = LOW = negative going signal -
I. PREAMP OUT (PHONE JACK). The signal from the mic preamplifier and compressor before the trans-
former. It is designed to be the cleanest output for direct to tape recording. The output phone jacks are dif-
ferent from the inputs. The phone jack outputs can only be unbalanced and are designed to bypass the output
transformers. Some people don’t like transformers. One of our favorite studio owners sez “I hate the sound
of bad transformers and love the sound of good ones”. These are great transformers and have very little
color. You can verify this by comparing the phone and XLR output one at a time. At “worst” the XLR out-
puts seem to have slightly more bottom and punch. When you insert a phone plug it cancels the XLR output
because it removes the transformer right out of the circuit. This unbalanced output is coupled with a MULTI-
CAP for you audiophiles out there. It will be fine driving balanced inputs as well as unbalanced inputs and is
designed for pro +4 dBu nominal levels The PIN-OUT is:
TIP = SIGNAL
SLEEVE = GROUND
and if you must use stereo plugs connect the RING to SLEEVE and/or if you are sending to a balanced input
connect LOW or negative to the SLEEVE at either end.
J. PREAMP OUT (XLR): A transformer balanced version of the mic preamplifier and compressor output.
Note that a 1/4 inch phone plug in the jack below will kill this output. The PIN-OUT is:
PIN 1 = CIRCUIT GROUND = SHIELD
PIN 2 = HOT = positive going signal +
PIN 3 = LOW = negative going signal -
K. INSERT INPUT (PHONE JACK): Like the LINE IN can be used balanced or unbalanced. This input
only goes to the EQ section. It is intended as a return for a noise gate or other processor between the mic pre
and EQ. It is also a way to bring in a second input to use the VOX BOX for two separate tracks. The PIN-
OUT is the same as the LINE INPUT and the same electronically.
BALANCED - (using a stereo phone plug )
UNBALANCED - (using a mono or stereo plug)
TIP = HOT = positive + TIP = SIGNAL
RING = LOW = negative - (RING = GROUND = SHIELD)
SLEEVE = GROUND = SHIELD SLEEVE = GROUND = SHIELD
L. INSERT INPUT (XLR): For balanced or unbalanced +4 line level sources. Transformer coupled XLR.
The PIN-OUT is:
PIN 1 = CIRCUIT GROUND = SHIELD
PIN 2 = HOT = positive going signal +
PIN 3 = LOW = negative going signal -
M. EQ OUT (PHONE JACK). The signal from the EQ and De-Esser before the transformer. The phone
jack outputs can only be unbalanced and are designed to bypass the output transformers. When you insert a
phone plug it cancels the XLR output because it removes the transformer right out of the circuit. This output
is also coupled with a MULTICAP. It will be fine driving balanced inputs as well as unbalanced inputs and
is designed for pro +4 dBu nominal levels The PIN-OUT is:
TIP = SIGNAL
SLEEVE = GROUND
and if you must use stereo plugs connect the RING to SLEEVE and/or if you are sending to a balanced input
connect LOW or negative to the SLEEVE.
N. EQ OUT (XLR): A transformer balanced version of “M”. This is also the final output or main output.
Note that a 1/4 inch phone plug in the jack below will kill this output. The PIN-OUT is:
PIN 1 = CIRCUIT GROUND = SHIELD
PIN 2 = HOT = positive going signal +
PIN 3 = LOW = negative going signal -
